Changes from v1:
- multi-planar rgb for YUV2RGBFUNC no longer uses an array in the stack,
  since that gave an overall 1% slowdown because some variables would no
  longer be stored in registers.

Ramiro Polla (5):
  swscale/yuv2rgb: prepare LOADCHROMA/PUTFUNC macros for multi-planar
    rgb
  swscale/yuv2rgb: prepare YUV2RGBFUNC macro for multi-planar rgb
  swscale/yuv2rgb: add yuv42{0,2}p -> gbrp unscaled colorspace
    converters
  swscale/x86/yuv2rgb: add ssse3 yuv42{0,2}p -> gbrp unscaled colorspace
    converters
  swscale/aarch64/yuv2rgb: add neon yuv42{0,2}p -> gbrp unscaled
    colorspace converters
